Compact pressure boosting system according to DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non self-priming, switched in parallel, vertically-mounted stainless steel high-pressure multistage centrifugal pumps in glanded versions. Ready for connection with stainless steel pipework, mounted on a base frame, including control device with all necessary measurement and adjustment equipment.

For fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.

For pumping drinking water, process water, cooling water, fire water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities) or other types of industrial water that do not attack the materials either chemically or mechanically and do not contain abrasive or long-fibre constituents.

Special features/product benefits

Heavy-duty system which satisfies all the requirements of DIN 1988 (EN 806)

WRAS/ KTW/ ACS approval of the pumps for all parts that come in contact with the fluid (EPDM version)

High-efficiency pump hydraulics of the Helix V series in connection with IE3 standard motor, including 0.75 kW and larger (optional for smaller motor power)

Bidirectional mechanical seals in the pumps for easy maintenance

Flexible lantern design permits direct access to the mechanical seal

The spacer coupling enables the mechanical seal to be replaced without dismantling the motor (from 7.5 kW)

Fully graphics-capable touch screen with 3-colour backlight for indicating the operating status operation/ fault/ acknowledged fault, and supporting symbols and plain text for menu navigation in six languages (out of up to 27 languages, with European and Asiatic characters selectable)

Manual-0-Automatic switch Preselection of the operating mode of each pump and manual operation in the event of a controller fault "Manual" (emergency/test mode available at mains power, motor protection available), "O" (pump switched off – cannot be switched on using the controller) and "Auto" (pump enabled for automatic mode via the controller)

Automatic, configurable pump cycling

Pump cycling by means of service life optimisation over operating hours.

Alternative: Pump cycling after a set time period, regardless of the operating hours

Alternatively by impulse: The base-load pump is cycled at each new demand, regardless of operating hours

Alternatively: with pump preselection: one pump can be permanently defined as the base-load pump. All peak-load pumps are changed on a running time optimisation basis.

Automatic, configurable pump test run (pump kick)

Can be activated/deactivated

Time between two test runs is freely programmable

Disabling times can be programmed as desired

Monitoring

Display of actual value of the system via a 0 – 10 Volt analogue signal for external measurement/display applications, 10 Volt correspond to the final sensor value
